More travelers are expected to hit the skies during this year's Thanksgiving holiday.

The Transportation Security Administration expects more than 25 million travelers to go through airport checkpoints between Nov. 16 and Nov. 26 — making it one of the busiest Thanksgiving holidays on record. It represents a 7 percent increase compared to last year.

That increase is expected to trickle down to Iowa's largest airport, and its administration is advising travelers to plan extra time this year.

For those planning to fly, this might mean longer lines at security or increased drive times to the airport. The Des Moines International Airport expects its busiest days to be the Tuesday and Wednesday before Thanksgiving (Nov. 22), and the Sunday after.

To prepare, the airport provides these tips:

Know which meal items to leave at home. Turkey, stuffing, pies and cakes are allowed through security as solids, but mashed potatoes and gravy — considered liquids — are not allowed in carry-on baggage.

Skip wrapping gifts. For those bringing gifts to family members, the TSA suggests waiting to wrap them until arriving at your destination, in case agents need to unwrap items as they go through security.

Arrive at least 90 minutes before your flight. This will leave plenty of time to navigate longer security and concession lines and arrive at your scheduled gate.

Research parking options before arrival. The most familiar parking spaces in Des Moines will likely fill up quickly. Passengers can look up all parking options, including prices, online before leaving their home.
